Laser surface treatment equipment

Abstract

The invention provides laser surface treatment equipment. A laser assembly, a reflection assembly and a polygonal rotating mirror are arranged, the laser assembly comprises a first laser emission source and a second laser emission source which are sequentially arranged from bottom to top, and the power of lasers emitted by the first laser emission source is different from that of lasers emitted bythe second laser emission source. The reflection assembly reflects the lasers emitted by the first laser emission source and the lasers emitted by the second laser emission source to different side faces of the polygonal rotating mirror. The polygonal rotating mirror reflects the received lasers to a to-be-treated part for surface treatment while rotating. The first laser emission source and thesecond laser emission source different in power are arranged at the same time, pretreatment can be carried out while metal surface oxide and pollutants are removed, prepares are made for the later derusting procedure, and therefore the surface treatment efficiency is improved, and cost is reduced; and the two laser emission sources are arranged up and down so that the occupied area can be reducedeasily.

Description

technical field [0001] The invention relates to laser technology and its application, in particular to a laser surface treatment equipment. Background technique [0002] The main principle of laser surface treatment is to irradiate the surface of the part with laser, the surface layer of the part and the pollutants absorb the laser energy, and produce vibration, ablation, gasification and other phenomena, so as to remove the rust on the surface of the part, ablation or gasification of the pollutants on the surface of the part, Thereby eliminating surface defects of parts and strengthening the strength of parts surface. [0003] The existing laser surface treatment equipment usually uses a single-channel low-power laser to repeatedly scan the surface of the part to achieve the purpose of surface treatment. The following methods are mainly used: [0004] (1) The object to be processed is stationary, and the irradiation position of the laser beam is changed; [0005] (2) The ...

AI Technical Summary

Problems solved by technology

[0012] The existing laser surface treatment equipment usually uses a single laser beam to scan the surface of the part multiple times, and adjusts the parameters such as laser output power and frequency of each scan in real time to achieve the final goal, and the processing efficiency is relatively low

Or use multiple laser equipment to perform degreasing, rust removal, surface pretreatment and other processes at multiple stations, but the cost is high and the area is large
